Abstract

A street pole comprising an antenna section with a coaxially mounted antenna around a pole. The antenna section having a length L and comprising at least one of the following features: —suspension with O-rings wherein the O-rings are each mounted at a distance Dr of 0.5*(1−½√2)*L from a respective end of the antenna; —a fix suspension at bottom; —a reduced outer diameter of the pole at at least one end (i.e. top end and/or bottom end) of the antenna; and—one of i) an extruded cable sleeve with opening in circumference over its full length for easy assembling and to spring mount the cable sleeve around the pole, and ii) a grooved pole with specifically shaped grooves for collecting residual particles at preferred locations.

The invention claimed is: 
     
       1. A street pole comprising:
 an antenna section, said antenna section has a length L and comprises antenna mounting tolerance features to enable mounting of a coaxial antenna around the pole with at least a local clearance in a range of 0.2 to 8 mm for providing a bending space for the pole, wherein the antenna section comprises at least one of the following antenna mounting tolerance features for attaining the bending space:
 suspension with O-rings wherein the O-rings are each mounted at a distance Dr of 0.5*(1−½√2)*L±10% from a respective end of the antenna; or 
 a reduced outer diameter of the pole at a bottom end and a top end of the antenna section; and 
 one of:
 an extruded cable sleeve with opening in circumference over its full length for easy assembling and to spring mount the cable sleeve around the pole, or 
 a grooved pole with axial grooves for collecting residual particles at preferred locations. 
 
 
 
     
     
       2. The street pole as claimed in  claim 1 , wherein the axial grooves have at least one of the following features:
 an axial sub groove at a bottom of the groove; 
 a rectangular cross section of the groove; 
 a V-shaped cross section of the groove; 
 a trapezoidal cross-section either widening or tapering inwards from an outer surface of the pole; or 
 a depth of groove being 1.05 to 2 times larger than a width of groove. 
 
     
     
       3. The street pole as claimed in  claim 1 , wherein at least one top end comprises at least the top end of the antenna section. 
     
     
       4. The street pole as claimed in  claim 1 , configured as a street lighting pole further comprising an antenna mounted around the antenna section, a luminaire section, a mid-pole section and a base section, wherein a sequence of mutually connected adjacent sections from base to top is: the base section, the mid-pole section, the antenna section and the luminaire section. 
     
     
       5. A luminaire comprising the street pole as claimed in  claim 4 , further comprising electric cabling at least extending through a core opening in the antenna section and electronic equipment in the mid-pole section and/or the base section and configured for driving a light source accommodated or (to be) accommodated in the luminaire section. 
     
     
       6. The street pole as claimed in  claim 1 , wherein the local clearance is in a range of 2 to 5.5 mm. 
     
     
       7. The street pole as claimed in  claim 1 , wherein the local clearance is in a range of 3 to 4.5 mm. 
     
     
       8. The street pole as claimed in  claim 1 , wherein the pole is the grooved pole with the axial grooves and wherein the pole is provided via a hot dipping coating process with a protective coating of Zinc-Iron alloy or Chromium. 
     
     
       9. The street pole as claimed in  claim 1 , wherein the reduced outer diameter of the pole is an indent in an outer surface of the pole provided at a location of at least one of the bottom end or at the top end of the antenna. 
     
     
       10. A method of manufacturing an antenna pole section, the method comprising:
 providing an antenna pole section with axial antenna cable guiding grooves in an outer surface of the antenna pole section over a full length of the antenna pole section, the grooves having at least one of the following features:
 an axial sub groove at a bottom of the groove; 
 a rectangular cross section of the groove; 
 a V-shaped cross section of the groove; 
 a trapezoidal cross-section either widening or tapering inwards from the outer surface of the antenna pole section; 
 a depth of groove being 1.05 to 2 times larger than a width of groove; or 
 coating the antenna pole section with a corrosion resistant coating. 
 
 
     
     
       11. The method of manufacturing an antenna section, comprising:
 manufacturing the antenna pole section according to  claim 10 ; 
 mounting antenna cables in the grooves; 
 providing antenna mounting tolerance means; and 
 mounting an antenna onto the antenna pole section.
